Process for preparing guanidino-functional monomers

A process comprising

• (a) combining
• (1) an amine compound comprising (i) only one or two primary aliphatic amino groups and (ii) only one secondary aliphatic amino group, primary aromatic amino group, or secondary aromatic amino group, and
• (2) a guanylating agent;
• (b) allowing or inducing reaction of said amine compound and said guanylating agent to form a guanylated amine compound;
• (c) combining
• (1) said guanylated amine compound, and
• (2) a reactive monomer comprising (i) at least one ethylenically unsaturated group and (ii) at least one isocyanato group;
• and
• (d) allowing or inducing reaction of said guanylated amine compound and said reactive monomer to form a guanidino-functional, free radically polymerizable compound.

A guanidino-functional, free radically polymerizable compound represented by

• the following general formula
• CH2═CHR1—C(═O)—O—R5—NH—C(═O)—NR4—R2—NH—C(═NR3)—N(R3)2 (I)
• wherein
• R1 is selected from hydrogen, alkyl, aryl, and combinations thereof;
• R2 is selected from hydrocarbylene, heterohydrocarbylene, and combinations thereof;
• each R3 is independently selected from hydrogen, hydrocarbyl, heterohydrocarbyl, and combinations thereof;
• R4 is selected from hydrogen, hydrocarbyl, heterohydrocarbyl, and combinations thereof;
• R5 is selected from hydrocarbylene, heterohydrocarbylene, and combinations thereof;
• with the proviso that R2 and/or R4 comprise(s) at least one aromatic moiety.
